What does Nokia's carl zeiss lens mean?

Nokia's mobile phone uses a carl zeiss-certified lens, but this lens is not the original lens. It's just a certified lens. To put it bluntly, this is a lens made by imitating the original lens structure of carl zeiss. Carl zeiss Lens is a German brand. Carl zeiss is a German multinational company, which is famous for producing optical products such as lenses and film cameras. Carl zeiss's glorious course in the history of lens manufacturing began in 1890 when the company's engineers invented the aspheric lens. In the same year, Protar lens came out; 1896, the plane lens came out, which established carl zeiss's authoritative position in chromatic aberration correction technology. 1902, Zeiss factory designed a Tessar lens, 1: 6.3. This lens is sharp and sharp, and the imaging quality is quite good. As an old optical enterprise with a history of 150 years, carl zeiss is also famous in the medical manufacturing industry. Its microscope, magnifying glass, medical endoscope, camera lens, glasses and other products are very famous in the world. Among them, the lens of Zeiss Factory has always been famous for its vivid imaging, clear details, bright surface, excellent anti-color cast and anti-reflective performance. Carl zeiss is a manufacturer of optical instruments with a long history, and its lens has always been synonymous with "nobility" in the field of traditional cameras. Many photographers are proud of having carl zeiss lenses. Carl zeiss lens has always enjoyed a high reputation in the industry, and it is called "Hawkeye" because of its ultra-clear imaging ability. Generally, only high-end cameras will be equipped with this lens. Carl zeiss, an old German optical manufacturer, has a history of 100 years, and has produced one of the few high-quality lenses in the world. Because of its unique color reproduction and imaging characteristics, photographers and enthusiasts all over the world can't put it down (but stay away from it because of its high price). High resolution, excellent color reproduction and almost no corner distortion. Faithfully provide high-quality photographic works. Among them, the lens marked with red T * is a product that Carl Zeiss is proud of. The imaging quality of digital camera mainly depends on the following three components: lens, CCD and image processing engine. Among them, the lens is the main receiving source of external light, and its quality directly affects the clarity and sharpness of imaging. The following is a brief introduction of several camera lenses produced in carl zeiss: * plane (plane lens) double Gaussian lens, which can correct various lens aberrations well. Since then, the design of standard lenses of various brands produced all over the world has benefited from Planner. *Sonnar (sonar lens) has deep detail fidelity and color balance skills. Different from the flat lens, Sona's imaging performance is more detailed and sharp. It is usually used to take photos and movies. *Distagon lens has a very wide field of view, and its wide-angle and telephoto performance are very good. It is also often used in photos and movies. *Tessar consists of three groups of four lenses. The final image is not only bright and transparent in the central part, but also clear in the details in the corner area, which is suitable for photo shooting. *Biogon (Biogon lens), a lens invented by Dr. Meta, caused great repercussions in the industry at that time. The biggest feature of the lens is that its wide-angle end will hardly produce lens distortion. * Hologon lens does not support large aperture, but the distortion of the lens at the wide-angle end is almost zero, and the imaging performance is excellent. Now let's talk about what a carl zeiss-certified lens is. Carl zeiss-certified lenses are not carl zeiss lenses. Simply put, it is a lens made by a third party. After meeting a series of test standards in carl zeiss, this lens was named carl zeiss. As for the advantages, there are some small advantages, such as smaller lens aperture (aperture value = lens focal length/lens aperture) and more light input; The photos taken are saturated in color and fresh and natural on the whole. Carl zeiss's original quality is not as good as these so-called certifications, and of course the price is not acceptable to ordinary consumers. Even the carl zeiss lens used in Sony cyber-shot cameras is only certified, not to mention the lens on Nokia phones. The "carl zeiss" on the mobile phone is just a brand-name label bought with money, and the authentication only shows that it is authorized by Zeiss, and it is not made by Zeiss factory. Zeiss factory only makes advanced camera lenses. The so-called Zeiss lenses of some Japanese manufacturers are actually authorized production, not the original factory. For example, the Zeiss head of Sony digital camera. Although the standard is unified, the original Zeiss lens and the authorized Zeiss lens have different optical quality because of the invisible differences in raw materials, management and labor. Just like a chain store selling tofu, the secret recipe handed down by our ancestors can be used in chain stores, but only the oldest store is the most authentic, because it also has historical and cultural things in it, which others can't learn. The camera of the mobile phone can't be the original Zeiss, and the real Zeiss lens, whether coated or structured, can't be compared with the mobile phone! If it is true, it is a waste of time. These lenses with Zeiss label are just the labels of some companies specializing in camera production, which may be no different from other mobile phone lenses, but generally speaking, certified cameras are better than ordinary cameras. Let's see how bad the quality of the so-called domestic 2.3 million pixels is. However, it should be reminded that "certification" does not mean "production". In the field of digital cameras and mobile phones, both Sony and Nokia's cameras claim to be certified by carl zeiss. However, these products are actually only produced by themselves according to carl zeiss standards, and have been recognized by carl zeiss, and they are not real carl zeiss products. The real "carl zeiss" factory stopped producing such low-grade lenses long ago. I believe you have already understood what carl zeiss lens is and what carl zeiss certified lens is, and you will no longer be so fascinated by carl zeiss on your mobile phone.
